Right, this is really bugging me..
I don't know what to look for.
the car drives fine off boost. If I put the foot down and change at 4krpm, all is fine. Anything above that, the car bogs down and I just hear the rumbling noise at round 10 psi. Boost slowly then reaches 15+ psi.
One time I wiggled the wiring loom, took the car out and it went 100% for 300m. Turned to come home and it was back to the rumbling noise again
Faulty ECU?
Faulty Wiring loom?
I've disconnected the blue temp sensor. Revs dip and it barely drives so it cant be that.
Disconnected the lambda sensor and it made no difference at all? Should it drive better it the lambda was at fault?
Could a wire to the boost switch be at fault? Or would that mean it would run crap at idle since the boost switch is wired to the idle switch?
The spark plugs are white indicating it isn't getting fuel at all on boost? Running seriously lean. Can throw up a pic if need be.
GIVE ME SOME SUGGESTIONS PLEASE
